متن کاملRadular ultrastructure of South American Ampullariidae (Gastropoda: Prosobranchia).
The radula of five species of South American Ampullariidae was analysed by Scanning Electron Microscope (SEM) with the purpose of enlarging new studies on the systematic of this family. The studied species were Pomacea canaliculata (Lamarck, 1822), Pomacea scalaris (d'Orbigny, 1835), Pomella (P.) megastoma (Gray, 1847), Asolene (A.) platae (Maton, 1809) and Felipponea neritiniformis (Dall, 1919...
متن کاملPomacea canaliculata (Gastropoda: Ampullariidae): life-history traits and their plasticity.
Freshwater snails belonging to the Ampullariidae family show noteworthy anatomical, physiological and ecological characteristics (Berthold, 1991), which have captivated scientific interest since long ago. However, few field studies have focussed on apple snail population dynamics (Burky, 1974; Lum Kong and Kenny, 1989). International concern about the Argentinean apple snail Pomacea canaliculat...
متن کاملFacultative and obligate symbiotic associations of Pomacea canaliculata (Caenogastropoda, Ampullariidae).
Pomacea canaliculata (Lamarck 1822) occurs mainly in lentic habitats throughout the lower Amazon basin and the Plata basin (Hylton-Scott, 1958; Martín et al., 2001). This Neotropical species has been introduced (ca. 1980) to several South East Asian countries for aquaculture, and has become a serious pest for rice and other crops (Halwart, 1994). Many Pacific islands are currently included in t...
متن کاملKaryotype description of Pomacea patula catemacensis (Caenogastropoda, Ampullariidae), with an assessment of the taxonomic status of Pomacea patula.
Mitotic chromosomes of the freshwater snail Pomacea patula catemacensis (Baker 1922) were analyzed on gill tissue of specimens from the type locality (Lake Catemaco, Mexico). The diploid number of chromosomes is 2n = 26, including nine metacentric and four submetacentric pairs; therefore, the fundamental number is FN = 52, No sex chromosomes could be identified. The same chromosome number and m...
